One reason we're not doing too many reviews of equipment at the moment, is primarily because of James Cigler. James has several reviews of current modules from Livewire and Plan B and I must say, they are the most informative and easy to follow reviews I have seen for modular synths. I have also managed to trick him into joining our Workspaces and Environment series.
If you're considering buying modules but are halfway confused on their true functions, here are some examples of his reviews:
Livewire: Vulcan Modulator
Plan B: Model 24 Heisenberg Generator
Livewire: Dual Cyclotron
